MOP-WRINGER.

Specification of Letters Patent.

Patented May 1, 1906.

Application filed April 28, 1904. Serial No. 205.333.

To all whom, it may concern:

Be it known that we, HERMAN M. REY- NOLDS and WILLIAM E. SHERWOOD, ofOneida, in the county of Madison, in the State of New York, have invented new and useful Improvements in Mop-Wringers, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to the class of mop- Wringers in which a presser-board is connected to the wringer-frame and adapted to be moved toward a stationary breast attached to the wringer-frame to express the water from the mop introduced b etween said presserboard and breast; and the invention consists in improved constructions of the component parts of the mop-Wringer, which is thereby rendered very efficient and convenient in its operation, as hereinafter described, and

as illustrated in the annexed drawings, in which- Figure 1 is a front elevation of a mopinvention. Fig. 2 is a vertical transverse section on the line W W in Fig. 1. sectional views on the lines X X, Y Y, and Z Z, respectively, in Fig. 2. Fig. 6 is a detail inner face view of a portion of one of the side walls of the wringer-frame, and Fig. 7 is a detail inner side view of a portion of one of the arms to which the presser-board is attached. 1

Similar letters of reference indicate corresponding parts.

A A denote two vertical plates which are disposed parallel and constitute side walls of the stationary wringer-frame, each of which walls is formed with a hook at, by which the wringerframe is hung on the top of the mop-pail P. To brace the portions of the pail on which the wringer 1s hung, as aforesaid, we form each of the side walls A with a straight down- Wardlyextending shank a, which is disposed adjacent to the hook (I. and bears with its entire length on the inner side of the pail directly opposite the hook, as shown in Fig. 2 of the drawings. The said shank is widened and convexed transversely to stiffen it and at the same time provide it with a broad convex bearing a corresponding to the Figs. 3, 4, and 5 are transverse curve of the inner side of the pail throughout the length of the shank, and thus securely support the wringer and obviate undue abrasion of the portion of the pail which is in contact with the shank a. Each of said shanks is formed at its lower end with an car a projecting inwardly from it at right angles to the shank.

The walls A A of the wringer-frame are provided with slots 0 c or other suitable openings for escape of the expressed water. Each of the said walls is formed with parallel flanges or ribs 1) 6 extending from the top to the bottom of the inner edge of the wall, and with a bracket 0, disposed beneath the wall and extending from the flanges b b v part way the width of the wall. The inner side of said bracket is provided with parallel ribs 0 0 extending lengthwise of the bracket and to the lower ends of the flanges b N, as shown in Figs. 2 and 6 of the drawings. Between these upright ribs b b are inserted the side edges of the breast B, consisting of a board or plate which is perforated for escape ofthe water expressed from the mop.

The outer surface of the breast B is provided with a horizontal groove 01, in which is embedded a rod e, which is formed at one end with a conical head e, countersunk in one o the side walls of the frame and provided on its other end with a nut c and serves to tie said walls to each other andretain the breast B in the frame. The end portions of the rod 6 engage recesses 6 a provided in the outer ribs of the walls, as more clearly shown in Fig. 2 of the drawings.

C re resents the presser-board, which is movab e toward and from the stationary breast B and serves to express the water from the mop introduced between them. This resser-board is carried on the upper portions of vertical arms D D, which are pivoted at their lower ends to the aforesaid ears a a projecting from the corresponding ends of the shanks a of the wringer-frame, as indicated at h The upper portions of the arms D D are each provided on therinner side with a pair of longitudinal parallel flanges f one of the flanges of each pair terminating at 1ts' gag expressed from the mop, and it is inserted with its side edges between the flanges f f of the arms D D and is sustained in its position by means of a transverse rod f embedded in 5 a groove f in the outer face of the presserboard substantially like the aforesaid rod 6. Said rod f 2 is fastened at its ends to the arms D D and firmly ties said arms together.

it denotes the bottom board or plate which extends from the base of the breast B and is disposed to allow the presser-board C to pass over it and is arranged with waterpassages between it and the said breast and presserboard, as indicated at g g in Fig. 2 of the I 5 drawings. This bottom board is inserted with its end edges between the rib extensions 0 c on the brackets c 0, formed 011 the wringer-frame, and through these brackets pass screws entering the ends of the bottom board, whereby the latter is held stationary on the frame and supported independently of the resser-board and breast, and thus adapted to be readily placed in position without requiring special fitting to either the Presser-board or breast. The most important features of said support for the bottom board h are the rigidity of brackets c c and the bearings of the flanges c c of said brack ets engaging the top and bottom of the board, 3 so as to prevent it from splitting in the operation of the wringer.

The resser-board C receives motion from a rock-shaft 7c, which is mounted at its ends in the side walls A A of the wringer-frame and has affixed to it a handle or lever L, by means of which the operator imparts motion to said rock-shaft. This rock-shaft has rigidly projecting from it two sectoral gears m, disposed, preferably, near the inner faces of 4 the side walls of the frame and engaging similar sectoral gears n, formed on the free ends of the arms or connecting-rods n, pivoted at their opposite ends to ears n n projecting outwardly from the outer flanges ff of the arms D D, as clearly shown in Fig. 2 of the drawings.

By means of links or straps Z, connected at their ends to the gears m n, the said gears are maintained in engagement, as shown in Figs.

l and 2 of the drawings.

By placing the gears m eccentric on the shaft is, as shown in Fig. 2 of the drawings, the pressure transmitted to the presser-board C is gradually increased during the operation of the leverL in squeezing the mop introduced between said resser-board and opposed breast B, and thus the described mop-wringer is rendered more eflicient in its operation.

In order to insure the return of the water 6 o issuing through the perforations of the presserboard 0 to the ,mop-pail and at the same time protect the operator, we employ a water shed or shield 1", which is applied to the outer face of the presser-board and extends across the entire perforated portion of said board and to the base thereof with space between them to conduct the expelled water down on the exterior of the presserboard and to the bottom board h, from whence said water passes through the adjacent passage 9 to the interior of the mop-pail. This shield consists, preferably, of an imperforate metallic plate, which is formed at its side edges with flanges r T, which are inserted between the edge portions of the presser-board and lugs s s, projecting from the outer flangesff of the arms D D, the bottom edges of which flanges rest upon the aforesaid shoulders f of said flanges, as shown in Figs. 1 and 3 of the drawings.

Dne of the important features of our invention, which will be readily observed, resides in the attaching of the bottom board to the wringer-frame independent of the breast and presser-board and in arranging the bottom board with passages between it and the bases of the resser-board and breast, which passages permit a free egress of the expressed water at both the rear and front edges of the said bottom board, and, furthermore, by providing the bottom board with rigid supports extending across the greater portion of the width of its end portions the board eflectually resists the strain of the pressure of the mop thereon incident to the squeezing of the mop between, the presser-board and breast.

Another feature of our invention resides in the employment of a removable shield arranged at the outer face of the presser-board, which shield serves to conduct the water issuing through the perforations of the presserboard into the mop-pail, and thereby prevent the water from coming in contact with the person operating the wringer. The detach ability of the shield permits convenient access to the rear of the presser-board for cleaning the board when required.

By forming the shanks a with the convex earings (1 extending the entire length of the shanks, as hereinbefore described, we strengthen said shanksand obviate wear and abrasion of the inner side of the pail incident to the contact of the shanks with said part of the pail.

Having claim is l. The combination, with the stationary wringer frame, stationary breast and the resser-board provided with perforations for escape of the expelled water, of a water-shed disposed across the exterior of the entire perforated portion of the presser-board and leading to the interior of the mop-pail, as set forth.
